Hi Aliaksandr,
Hoping you may be able to assist here.
I have Santa Fe Limited 2021 and want to look at fitting LED spotlights and control via relay from the Hi-Beam control arm on the steering wheel.
However I am having difficulty identifying the Hi-Beam fuse and/or relay’s from the handbook or from the information above. There is nothing identifying any headlamp fuse or relay??
Are the headlamps under a combined fuse with other items?
Thanks.
